SL23EP04SI-2 Equivalent & Substitute Parts

Part Overview

The SL23EP04SI-2 is a clock buffer IC manufactured by Skyworks Solutions Inc., designed for 220MHz clock distribution applications. This device features a 1:4 input-to-output ratio with LVCMOS output in an 8-SOIC package. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL23EP04SI-2 is determined by the following critical parameters:

• Maximum frequency capability (220 MHz minimum required)
• Input-to-output ratio (1:4 configuration)
• Output logic family (LVCMOS)
• Supply voltage compatibility (3.3V nominal operation)
• Operating temperature range (-40°C to 85°C)
• Surface mount packaging suitable for PCB integration

The SI53365-B-GT is identified as a substitute based on shared manufacturer origin, compatible supply voltage range, matching operating temperature specifications, and LVCMOS output configuration. However, differences in package type, frequency rating, and output ratio must be evaluated for specific application requirements.

Engineering Selection Recommendations

The SI53365-B-GT represents an active product alternative from the same manufacturer with confirmed RoHS3 compliance and extended moisture sensitivity rating. Selection of this substitute requires evaluation of the following factors:

• Package footprint change from 8-SOIC to 16-TSSOP necessitates PCB layout modification
• Output ratio increase from 1:4 to 1:8 provides additional clock distribution channels
• Maximum frequency specification of 200 MHz remains within acceptable range for most 220 MHz-rated applications operating below maximum rated frequency
• Supply voltage range expansion (1.71V minimum) provides broader operational flexibility
• Active product status ensures continued availability and manufacturing support

For applications requiring exact 1:4 ratio configuration or strict adherence to 8-SOIC packaging, alternative sources or custom solutions may be necessary.

Frequently Asked Questions (FAQ)

Q: Can SI53365-B-GT directly replace SL23EP04SI-2 without PCB modification?

A: No. The SI53365-B-GT uses a 16-TSSOP package compared to the 8-SOIC package of the SL23EP04SI-2. PCB layout changes are required for pin-to-pin compatibility and proper signal routing.

Q: What is the impact of the 1:4 to 1:8 ratio change?

A: The SI53365-B-GT provides eight output channels instead of four. Applications requiring exactly four outputs must either use only four of the eight available channels or implement external gating logic.

Q: Is the 200 MHz maximum frequency of SI53365-B-GT sufficient for SL23EP04SI-2 replacement?

A: The SI53365-B-GT supports 200 MHz operation. Applications operating the original device below 200 MHz are compatible. Applications requiring operation above 200 MHz must source alternative components.

Q: What are the supply voltage compatibility considerations?

A: Both devices operate within the 3.3V nominal supply range. The SI53365-B-GT extends minimum supply voltage to 1.71V, enabling operation in lower-voltage systems. Standard 3.3V supply designs are fully compatible with both devices.

Q: How do the moisture sensitivity levels differ?

A: SL23EP04SI-2 specifies MSL 2A with 4-week floor life. SI53365-B-GT specifies MSL 2 with 1-year floor life. The SI53365-B-GT provides extended handling time before reflow soldering is required.

Q: Are both devices RoHS compliant?

A: SI53365-B-GT is confirmed ROHS3 compliant. RoHS status for SL23EP04SI-2 is not specified in available documentation. Verify compliance requirements with your procurement or quality assurance department.
